Trivia

References

There is a cheat code that replaces Kain's weapon with a cardboard tube, with Kain uttering "Fear the Tube". This is a reference to the popular web comic Penny Arcade and its "Cardboard Tube Samurai" character.

In one of the larger rooms in Vorador's Mansion, you can see a large painting. It is a portrait of a woman's face. However, the interesting thing is that she may be a reference to Umah, the female vampire from Blood Omen. If you look closely at her forehead and the sides of her face, you can make out tattoos similar to Umah's. In fact, one event that was removed from the game was the appearance of a pre-vampiric Umah.

Turel

The boss monster Turel, who Raziel encounters later in the game, was cut from the very first Soul Reaver. Although Turel was mentioned in Legacy of Kain: Soul Reaver as one of Kain's vampire clan leaders and his disciples could be found in the game, he himself was missing without any plot-related explanation.
Furthermore, a strategy exploiting Turel's weakness is needed to defeat him in Defiance, similar to the bosses in Soul Reaver.
